Splet07. apr. 2024 · Interestingly, a nonporous thin PDMS film formed on the surface layer of the sponge due to the overflow of excess PDMS. For the establishment of microstructure on the thin film, a flexible woven wire mesh (# 3000-mesh) with thickness of 70 μm and a punched plate with 500-μm diameter array hole were mounted independently on the … SpletThe sponge exhibited good sensitivity of 0.1145 kPa −1 in the low-pressure range (0–6.5 kPa), short response time (70 ms), and durability for over 2700 s (6000 cycles). The gauge factor of the PVA/H 3 PO 4 @PDMS sponge was 5.51, 1.49, and 0.33 at the strain range of 0–10%, 10–30%, and 30–80%, respectively.

Splet17. sep. 2024 · We compared the properties of the fabricated magnetoactive PDMS sponge with (PDMS:sugar:iron microparticles = 1:3:3 by weight) and without iron microparticles (PDMS:sugar = 1:3 by weight). The porous microstructures of both samples were confirmed by optical microscopy, as shown in Fig. 3 a and b. Splet27. avg. 2024 · The PDMS sponge only needed 0.069 MPa force to realize the compression ratio of 90%, which it still maintained after over 50 cycles of compression. In addition, the porous PDMS sponge exhibited an excellent oil absorption and an outstanding reusability, which were potentially useful in water purification. teenage mutant ninja turtles funko pop
